T0 all wil/0m, it Tim/y concern:

Beit known that l, WILLIAM D. GOLD, a citizen of the United States, residing at Carthage, in the county of Smith and State of Tennessee, have invented certain new and useful Improvements in Stoves; and I do declare the following to be a full, clear, and eX- actdescription of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in stoves, and especially to a stove or heater with a base-burner and spiral feed, whereby the fuel may be delivered to the grate by being thrown laterally by the feed-disk, means being provided for drying the fuel byits being spread upon a marginal grate, where it is subjected to a hot-air blast before reaching the grate on which the combustion takes place.

The invention relates, further, to a heater for various purposes having various combinations and arrangements of parts, which will be hereinafter more fully described and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form part of this application, and in which drawings similar letters of reference indicate like parts throughout the several views, in which- Figurel is a central vertical sectional view through my improved heater. Fig. 2 is a detail perspective of an air-inlet or ventilating portion of the heater. Fig. 3 is a detail perspective of the spiral feeding-disk. Fig. et is a perspective View of a. hot-air chamber over which the spiral feed-disk telescopes. Fig. 5 is a detail view of the shaking-lever and stationary grate. Fig. 6 is a sectional View on line G 6 of Fig. l. Fig. 7 is a cross-sectional view taken on line 7 7 of Fig. l. Fig. 8 is a cross-Sectional view on line 8 S of Fig. l. Fig. 9 is a cross-sectional view on line 9 9 of Fig. l. Fig. l0 is a cross-sectional View on line 10 of Fig. l; and Fig. ll is a cross-sectional view on line ll of Fig. l.

Reference now being had to the details of the drawings by letter, A designates the base portion of the heater, having a flanged top and containing an ash-pan A'. This base portion is provided with a suitable door, whereby access may be had to the interior of same, and the bottom of said portion is apertured to receive the pipe B2. At the upper end of the base portion is a iiange A4, which forms a support for the superstructure of the stove, said ange being provided with apertures B and B', Fig. 1l, through which the branching pipes B2 and B4 pass. Resting on a shoulder A5 of said flange A4 is the grate C. This grate, as shown in Fig. ll of the drawings, has a series of apertures arranged on the arc of a circle, each aperture having its longitudinal edges coincident with radiallines from the center of the grate, and has, preferably, lugs C' about its circumference, which lugs are adapted to rest upon said shoulder A",on whichitremainsstationary. Atthecenter of the grate, from which the spokes D radiate, is a pin D', with a depression around its base, serving as a pivot on which the inner end of the shaking-lever M, also the spiral feed-disk E, turns.

Fis a central hot-air box or chamber, a detail of which is shown in Fig. 4 of the drawings. This box or chamber has a circular wall which is perforated, as at F', and has an open-ended tube F2, rising about a central aperture in said box. This box is adapted to be seated on the radiating arms D, with the open-ended tube F2 about the central pin D', and to substantially fill the space within the inner circular margin of the grate, as shown in Fig. l of the drawings.

Resting on the apertured portion of the grate is a grate-cover G, a top plan view of which is shown in the sectional view Fig. 1l. This grate-cover has a series of rectangular solid sections and outlined apertures G' therein, which register with the apertures in the grate, but which cover may be turned so as to close or partially close the apertures in the grate. By having the apertures in the grate C with their longitudinal edges converging toward the center of the grate, and the apertures in the rotatable grate-section G superimposed, being of rectangular shape, it will be observed that when the grate-section G is partially rotated in the act of bringing the two sets of apertures into registra- IOO tion the outer portion of the apertures will first register, which will cause the draft and heat to be thrown outward or toward the inclosing wall of the fire-chamber. Said gratecover has a socket G2, in which one end of the shaker-lever G3 is held. This lever has an aperture in its outer angled end to receive the handle G. Said shaking-lever is bent as shown in Fig. 1 and passes down in the space between the outer margin of the grate and the inner margin of the flange A5.

The spiral feed E before referred to consists of a box, circular in form, open upon its bottom, and having notches Eabout its lower marginal edge, spaced apart about the circumference of said box, also has a series of apertures e' in its circumference, which may be brought into registration with the apertures in the hot-air box, as shown in Fig. l of the drawings, when said feed-disk has been telescoped over the hot-air box. Then said feed-disk is adjusted in place, as shown in Fig. 1 of the drawings, the under surface of its top rests upon the upper edge of the hotair box. On the top of said disk are the spiral feeding-arms 1432 (shown in Figs. l and 3 of the drawings,) and surrounding the upper portion of the feed-disk isa marginal grate H, which is shown in Fig. l of the drawings, and is provided with perfor-ations through which the fuel is allowed to fall onto the grate below. This marginal grate is provided so as to allow the hot air which issues from the registering apertures in the hot-air box and the feed-disk to pass through said marginal grate, whereby said fuel may become partially dried before it falls upon the grate below where the combustion takes place.

The superstructure of the heater is made up of several compartments superimposed one upon the other, each section, which is made up of two concentric walls, forming closed compartments having apertu res,where by communication is had between one compartment and another.. Suspended from the upper edges of the compartment K is a funnel-shaped wall J, to the lower end of which is secured the magazine L, the upper end of which is outwardly flared, and fitted over said upper flaring end is a cover L', which may be removed when it is desired to fill the magazine. The lower end of said magazine is disposed a slight distance above the upper end of the rotary feed-disk, whereby the coal will fall by gravity upon the top of the feedingdisk, and as said feeding-disk is caused to make a partial revolution the coal will be thrown laterally by means of the spiral flanges on said disk and caused to fall upon the marginal grate and onto the combustiongrate below.

Mounted on the central pin of the stationary grate is one end of a shaking-lever M, which fits into and practically fills a depression about the base of the pin left for the purpose, said lever being made of spring-steel and has a lug or projection m on an angle portion thereof, which projects upward and is designed to engage one of the notches E in the feeding-disk. The outer portion of said shaking-lever is angled, as clearly shown in Figs. l and 5 of the drawings, and is adapted to receive a handle in its outer apertured end, whereby said lever may be given a lateral swinging motion for the purpose of imparting a rotary movement to the feed-disk when said lug M is seated in a notch E of the feeding-disk. Near the end of said lever the steel portion rests on a bar M, passing from one to the other of the spokes and seated at each end into them, by which means and the elasticity of the lever the lug remains seated in the notch E of the feed-disk until the outer end is pressed down by the hand to remove it around to another notch and drawing it back for the purpose of imparting a rotary motion to the feeding-disk. By a succession of similar movements the feeding-disk may be given a complete rotary motion. By means of this lever the feeding-disk may be turned so that the apertures in the hot-air chamber and the feeding-disk will be brought into registration, or said apertures closed, accordingly as it is desired to allow or prevent hotair passing from the interior of the hot-air chamber through said apertures into the combustion-chamber.

In order to feed air into the space between the walls where it may be heated for conveyance to the rooms, also to feed air into the interior of the stove for combustion purposes, a forked pipe is provided, as shown in Fig. 2 of the drawings. The air enters through the pipel?, which is forked, having two branches B3 and B", the former of which branches Bl opens into the space between the inner cylinder and the outside wall of the heater, said branch passing through an aperture in the flange A4 and terminating, as shown, a slight distance above said flange. The air which enters the heater through branch B3 is for the purpose of combustion and passes first into an annular channeled compartment. (Shown on an enlarged scale in Fig. 2.) This channeled chamber is divided longitudinally by two partition walls N, making three compartments, into the upper of which the branch pipe B:3 enters. The location at which it enters is at the back of the heater. From its entrance the air passes both ways along the upper one of said channels (which extend all the way around the inner circumference of the inner wall of the second compartment of the heater) until it comes to the closed ends of the channels which moet at the front side of the stove just opposite where the air enters. IIere the partitions do not run quite out to the closed end of the channeled compartment N, and the air passes down in the direction of the arrow in Fig. 2 of the drawings, a part of it going into the middle channel and a part into the lower one. It has by this semicircuit of the stove become much heated, and the part that enters the lower IOO IIO

channel issues through the openings or ventilators n n into the interior of the stove and helps to support combustion. The portion of the air that enters the middle channel returns along said channel to near the point where it entered the upper channel, whence it is conveyed by pipe N3 into the interior of the hotair box very much heated, from which it issues through the apertures therein into the combustion-chamber,drying the fuel and aiding in supporting combustion. The air that enters between the concentric walls in the lowest compartment above the ash-pit through pipe B4, which is also at the back of the stove, passes around the stove between the walls both ways until it comes to the front, then rises through the aperture in the first horizontal partition into the second compartment or story, whence it returns to the back part of the stove and rises through the aperture in the second horizontal partition into the next story, and thus it sweeps in a current back and forth around the combustion-chamber between the stove-walls, gathering heat as it goes and rising through the apertures in the partitions from compartment to compartment until it reaches the topmost one, whence it may be conveyed t0 registers in different rooms through pipes leading from said compartment at the top of the heater or emitted into the room where the stove is situated through the aperturespp, which registerwith similar openings in a sliding band that surrounds that part of the stove and which may be closed at pleasure.

As shown in Fig. l of the drawings, the stove has a door in the superstructure or stove proper, through which access may bc had into the interior of the stove for kindling the fire:
